> Company newsRolling bearing hardness
2017-12-04
Bearing on the
hardness, inner and outer rolling ring bearings and PTFE flexible
bearings with high-chromium steel GCr15 or GCr15SiMn two kinds of
bearing steel, the finished bearing rings hardness Rockwell HRC60-65;
finished bearing rolling body hardness in Los HRC60-66. Among
them, GCr15 bearing steel ball hardness in the Rockwell HRC62-66 range;
GCr15SiMn bearing steel roller hardness in Rockwell HRC60-64, the ball
in the self-lubricating thrust washer HRC60-66 range Inside. Perhaps
you do not understand what Rockwell hardness HRC is the concept of
oil-free self-lubricating composite bearings, for example: the hardness
of household knives blade is generally around HRC50, surgical tools and
military tools to be more pure steel, hardness Also within Rockwell HRC60. Machine tool metal turning with the hardness of the conventional alloy head is also about Rockwell HRC62 ~ 65. The
hardness of rolling bearings is relatively hard, finished bearings to
further processing must use special equipment and tools.
